The \(\chi ^2\)  contributions of 77 Higgs search channels from the LHC and the Tevatron
are evaluated using HiggsSignals, see [1]},
where a complete list of references can be found.
The \(\chi ^2\)  contributions from the limits from searches for the heavy
neutral MSSM Higgs bosons in
the \(H/A \rightarrow \tau ^+\tau ^-\)  channels are evaluated using the code
HiggsBounds [2]}, [3]}, which incorporates the
results of CMS searches [4]}, [3]} with \(\sim 25~{\rm fb}^{-1}\)  of
8 TeV data. The contributions from the two
possible production modes, \(gg \rightarrow H/A\)  and \(b \bar{b} \rightarrow H/A\) , are
combined in
a consistent manner, depending on the MSSM parameters.
The results from HiggsBounds have been compared
with the published CMS analysis, and are in very good agreement [3]}.
The corresponding \(\chi ^2\)  contribution is labelled as “2D likelihood” in
Table REF .
For the corresponding constraint with \(~13\)  fb\(^{-1}\)  of 13 TeV data,
we implement an approximate treatment of the
\(\chi ^2\)  contribution using
the preliminary result of ATLAS [7]},
as we describe in more detail below.
Limits from other Higgs boson searches are not relevant for the
investigation in this paper and are therefore not included.
